SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 349,781, dated September 28, 1886. Application filed March 15, 1886. Serial No. 195,242; (No model.)
no punctured at the line of separation, pulled apart byan accelerated motion, and then two sheets are conveyed away in one direction and laid one on the other, and then the next .two sheets are carried, away in another direction and laid one on the other, and in both instances the two sheets are folded together into four or eight thicknesses, as in the delivery of newspapers. V
My improvements consist in the'combination, with the belts and pulleys, of stationary deflecting-bars and accelerating and nipping wheels, and means for raising and lowering the same, and belts that convey the sheets off in different directions, and lifting-frames to raise one sheet while the other runs in beneath the same, and guide-bars and dampers that prevent vibration of the lifting-frames as they are raised with the sheet.
By my improvements great accuracy is ob- 6 tained in the register, and there is no risk'of the sheet becoming obstructed or one sheet interfering with the next.
,In the drawings, Figure 1 is a vertical section representing the various pulleys, belts, Fig. 2i's a separate view of the accelerating-wheels in their depressed positions. Fig. 3 represents the devices that may be made use of for raising and lowering the accelerating-wheels. Fig. 4 is a plan of the belts and parts that receive the sheets and give' 5 partially separates such web by puncturing the same, as usual. The belts 4 and 5, passing from the pulleys 6 to the pulleys 7, serve to convey the web along, and the bars 9 and 10 aid in supporting and guiding such sheets to the nipping and accelerating wheels 12 and 13.
These latter are sufficiently far from thecylinders 1 and 2 to allow one sheet to pass clear of the cutter 3 before it is seized by the accelerating-wheels. The accelerating-wheels are preferably located; so as to act upon the margins and blank portions of the paper, and they are'upon shafts 14 and 15, supported in bearings '11, that slide vertically in the frame of the machine, and any suitable mechanisn1- such, for instance, asea'ms 16 and connectingrods 17-is employed for raising and lowering the bearings 11, and the cam is timed so that the wheels12 and 13 occupy their elevated position while two sheets pass through, and then occupy their depressed position while 20 and 21 of guide-bars diverge from the wheels 12 and 13, and between them are the stationary bars or plates 22. When the nipping and accelerating wheels are in a raised position, two sheets are passed off in succession between the ranges 20 and 22 of guide bars or plates, and when depressed the next two sheets pass off between'22 and 21. The ranges 32 and 33 of belts pass around the pulleys 30, 31, 34, and 35, and there are tightenerpulleys 37 and 38 for the belts, and the pulleys 36 serve to change the course of the sheets and cause them to pass off horizontally and through between the pulleys 34 and 35, and the two middle belts or tapes in the ranges of belts or around the respective pulleys 3940. There are two ranges of stationary guide-bars, 41 and 42, that extend from the pulleys 34 35 across, over, and parallel with the first folding-rollers '47 to the frame 45 of the machine, or nearly so. The range of bars 41 is connected with and held by the cross-bars 43, and the range of bars 42 is connected together and held by the cross-bars 44, and there is a range of bars, 46, projecting from the head-bar 48 and forming a lifting-frame, the head-bar 48 having guides 49 for the slide-bars 50, and revolvingv cams 51 serve to raise or lower the liftingframe bodily. The bars 46 are between the bars in the respective ranges 41'and 42, and when depressed these bars 46 lie upon the cross-bars 44, and the first sheet carried up and over the pulleys 36 and 35 is carried in above the bars 42 and 46, and it is stopped by the fence 54. Then the lifting-frame is raised bodily, and with it the first sheet, and the next sheet passes in beneath the bars 46 upon the next two sheets pass through. The ranges I tapes pass beyond the pulleys 34 and 35 and ICO the bars 42, and the folding-knife 56 is brought down upon the center of the sheet to fold the same, and the rollers 47 carry the folded sheet away and deliver the same either to a second folding device or discharge the sheet in any desired manner.
In lifting the frame the bars 46 are liable to vibrate. I prevent this by providing blocks 60, of rubber or similar material, over the respective bars 46 and upon the under sides of the bars 43. The shape of the cam 51 is such that the lifting-frame is partially lowered before the blade 56 descends to fold the sheets, so that the sheets may draw off easily. The pairs of pulleys 39 40 are close to the foldingrollers 47, and they act to'insure the proper delivery of the sheets by moving them across between the bars 41 42 to the fence 54, and it is preferable to use only two pairs of these pulleys, as shown, so that there is no risk of the sheets being detained by the same in the folding operation. The sheets that are delivered between the ranges of bars 21 and the bars or plates 22 pass between the tapes 32 33 and the pulleys and 31, and all the parts after the plate 22, and before described, are duplicated, and the operations are the same as before set forth, the reference-numbers being primed for greater convenience in designating the parts.
I claim as my invention 1. The combination, with. the cutting-cylinders 1 and 2 and the belts 4 and 5'and their pulleys, of the nipping and accelerating wheels 12'and 13 and the shafts and bearings for the same, and means, substantially as described, for raising and lowering such nipping and ac celerating wheels, and the ranges of bars 20 21, and stationary bars or plates22, and the respective pulleys and tapes for conveying away the sheets, substantially as set forth.
2. The combination, with the folding-rollers 47, and folding-blade 56, and ranges of bars between which the sheets to be folded are passed, of the ranges of tapes and pulleys for bringing the sheets to the folding apparatus, and the pulleys 39 and 40 in advance of the pulleys 34 35 and adjacent to the ends of JOHN BROOKS. \Vitnesses:
